Apparatus groups • Group I - Mines susceptible to firedamps • Group II - Other places • Gas groups(needed only for Ex d and Ex i) • IIA (e.g. Propane) • IIB (e.g. Ethylene) • IIC (e.g. Acetylene and Hydrogen) • Zones • Zone 0 - continuously • Zone 1 - occasionally • Zone 2 - in abnormal conditions • Temperature classes Ex nA EEx nA Ex e EEx e Ex p EEx p Ex d EEx d Zone 2 /Category 3 in abnormal conditions Zone 1 / Category 2 Occasionally Zone 0 Category 1 Continuously Ex e EEx e Ex p EEx p Ex d EEx d Not suitable for motors T1 T2 T3 T4 T5 T6 450°C 300°C 200°C 135°C 100°C 85°C IEC and EN standards

  3. II 2 G / D 0081 • Gas or Dust • Equipment Category (Zone 1) • Group of equipment for Surface • Use in explosive atmosphere • ExNB • CE-marking EEx d II C T4 Marking (EN) Marking according to ATEX-directive Standard marking according to EN-standards • EEx - Explosion protected apparatus (Euro Norms) • Type of Protection • II - Group (other than mines) • A, B, C - Gas groups • Used only with protection types d and ia/ib • Temperature Class

  4. Ex nA II T3 • EEx - Explosion protected apparatus • nA - Type of Protection • II - Group (other than mines) • A, B, C - Gas groups • Used only with protection types d and ia/ib • Temperature Class T1 T2 T3 T4 T5 T6 450°C 300°C 200°C 135°C 100°C 85°C Marking (IEC)

  5. ATEX Certified • Frame sizes 71-315 ATEX certified • Flameproof 80-315 • Non-sparking 71-315 • Dust ignition proof 71-315 • Increased safety 80-315 • Frame sizes 355-400 certification ongoing, ready by end of 2002

  6. Directives Marking Until 29.2.1996 1.3.96-30.6.2003 From 1.7.2003 76/117/EEC, Valid Valid 79/196/EEC and 82/130/EEC Valid Valid 94/9/EC (Atex) Basics of ATEX directive and timetable ATEX-directive (94/9/EC) • Compulsory after end of June 2003 • Covers all equipment, which will be installed in hazardous area in EU(also non-electrical devices) Requirements are divided in three categories: • Technical requirements from harmonised EN-standards • Health and Safety aspects • Production Quality requirements Timetable • ABB delivered the first ATEX certified motor in 02/1999

  7. ATEX directive - Requirements • Technical • All technical requirement based on harmonised EN standards • Harmonisation • New EN standards cover all EU countries • Health and Safety • All requirements focus on safety instructions • All equipment must be delivered with instructions for safe: • putting into service, use, assembling and dismantling, maintenance, installation, adjustment • In practice manuals (in English) and safety instructions (official language of the country and in English)

  8. EC Declaration of Conformity Directive 94/9/CE (ATEX): The only document which is mandatory to be given with each delivery is: EC Declaration of Conformity. With this document ABB takes the commitment and responsibility that the products respect the ATEX directive. This document gives information on; - product quality assessment notification - EC type examination certificate (with reference numbers).
